1. Set the function dial to V .
2. Press SELECT to select DC or AC. appears for AC voltage measurement.
3. Touch the black test lead to the circuit.
4. Touch the red test lead to the circuit.
If the meter is set to manual range and you measure an overrange input, OF will display. The
meter will return to standby mode when you remove the input.
